Cryoablation in Combination (or Not) With Pembrolizumab and Pemetrexed-carboplatin in 1st-line Treatment for Patients With Metastatic Lung Adenocarcinoma
Condition(s) studied
Investigational drug(s) / intervention(s)
Cryoablation: Cryoablation will be performed by a specialized radiologist, percutaneously, ie "through the skin". The operation is performed under general anesthesia, under the guidance of the scanner. The images from the scanner make it possible to precisely insert and place a needle at the level of the tumor to be treated. Intense cold will be produced by the needle and will destroy the cancer cells by freezing (temperatures of -40 °C). Freezing is localized to the tumor, the rest of the organ will not suffer from the cold. The aftermath of the intervention causes only minimal pain and in most cases does not require pain treatment. As the operation is minimally traumatic, the risk of complications is low. Hospitalization is around twenty-four hours and usual or professional activities can be resumed very quickly.
Pembrolizumab: Pembrolizumab will be prescribed and administered at the dose recommended by market authorization.
Pemetrexed: Pemetrexed will be prescribed and administered at the dose recommended by market authorization.
Carboplatin: Carboplatin will be prescribed and administered at the dose recommended by market authorization.
Study summary
This study aims to compare the one-year survival benefit of the association of cryoablation-pembrolizumab-pemetrexed-carboplatin versus pembrolizumab-pemetrexed-carboplatin in metastatic lung adenocarcinoma patients.
This is a multicenter, prospective, open-labeled, 2-arm comparative randomized (1:1) phase III trial.
Patients will be randomized with a 1:1 ratio into:
* Arm A (experimental arm): cryoablation of one visceral lesion or bone metastasis excluding liver and sclerotic bone metastases combined with pembrolizumab and pemetrexed-carboplatin prescribed as per market authorization.
* Arm B (standard arm): pembrolizumab and pemetrexed-carboplatin prescribed as per market authorization.
Pembrolizumab and pemetrexed-carboplatin will be prescribed and administered at the dose recommended by market authorization.
Cryoablation treatment should be performed within 6 weeks after the first administration of pembrolizumab. No treatment switching permitted.
Eligibility
Primary outcome measure(s)
- 1-year overall survival rate — 1 year
Overall survival (OS) is defined as the time interval between the date of randomization and the date of death (from any cause). Patients alive will be censored at the date of last follow-up or last patient contact. One-year OS rates will be compared between arms.
